基于电转气反应热应用和合作博弈的电转气装置容量规划

Capacity Planning of Power-to-gas Devices Considering Reaction Heat Recovery and Cooperative Game

针对电转气装置目前普遍存在的效益较低的现状,计及了电转气反应热的利用,并考虑了加强与综合能源主体的合作,从这两方面实现了电转气产业链的延伸和产业模式的创新。通过计及电转气放热、碳交易等,挖掘了电转气的盈利空间;基于合作博弈,提出了以含电转气的综合能源联盟净收益最大为目标的系统运行模型,基于Shapley值对联盟的每个主体进行了公平、合理的利润分配机制。此外,还对风电和热电联产机组间的利益冲突进行了分析,并进行了碳交易价格和电转气用电成本的灵敏度研究。分析结果表明,联盟的形式有助于电转气企业的投资与盈利,碳交易价格决定了电转气容量上限,用电成本直接决定了电转气投资与否。

In view of the current situation of the generally low power-to-gas benefit,this paper extends the power-to-gas industrial chain and brings forth new ideas on the industrial model by taking into account the power-to-gas heat recovery and strengthening the combination between the main bodies of the integrated energy system.With the heat recovery,carbon trading and so on in consideration,this paper explores the power-to-gas profit space firstly.Based on the cooperative game,it proposes a system operation model then aiming at the maximum net income of the regional integrated energy alliance containing power-to-gas.Also,it constructs a fair and reasonable profit distribution mechanism for each subject of the alliance based on the Shapley Value method.Additionally,the conflict of interest between wind power and combined heat and power unit is discussed,and the sensitivity studies of carbon trading prices and power-to-gas costs are performed.The analysis results show that the form of the alliance is conducive to the investment and profit of power-to-gas.The carbon trading price determines the upper capacity of the power-togas devices and the electricity costs will directly determine whether to invest in power-to-gas.
